Hexahalometallate salts of trivalent scandium, yttrium and lanthanum: cation-anion association in the solid state and in solution was written by Champion, Martin J. D.;Levason, William;Pugh, David;Reid, Gillian. And the article was included in New Journal of Chemistry in 2016.Application In Synthesis of 1-ethyl-2,3-dimethylimidazolium chloride This article mentions the following:
The hexahalide salts, [NBu4]3[LaCl6] (1), [BMPYRR]3[LaCl6] (2, BMPYRR = 1-butyl-1-methylpyrrolidinium), [EMIM]3[MX6] (EMIM = 1-ethyl-3-methylimidazolium; M = La, X = Cl (3), Br (4), I (5); M = Sc (6), Y (7), Ce (8), X = Cl) and [EDMIM]3[MX6] (EDMIM = 1-ethyl-2,3-dimethylimidazolium; M = Y (9), X = Cl; M = La, X = Cl (10), I (11)) were prepared and x-ray crystal structures determined for several of them, with a view to probing the effect of varying the trivalent metal ion, the halide and the countercation on the structures adopted in the solid state. The crystal structures of the EMIM and EDMIM salts show extensive H-bonding between the halide ligands and organic cations; based upon the H-bonding distances, this appears to be strongest for the [EMIM]3[MCl6] salts, becoming progressively weaker for heavier metal ion or halide. In terms of the cations, changing from EMIM to EDMIM also reduces the strength of the H-bonding. The strength of the cation-anion pairing in solution also was probed in solution via NMR spectroscopy where possible (45Sc, 89Y and 189La) and, for the EMIM salts, via the shift of δ(H2) relative to [EMIM]Cl at a standard concentration The trends observed in solution mirror those determined in the solid state. In the experiment, the researchers used many compounds, for example, 1-ethyl-2,3-dimethylimidazolium chloride (cas: 92507-97-6Application In Synthesis of 1-ethyl-2,3-dimethylimidazolium chloride).
1-ethyl-2,3-dimethylimidazolium chloride (cas: 92507-97-6) belongs to imidazole derivatives. Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. The pharmacophore of imidazole exists in bioactive compounds including amino acids, plant growth regulators and therapeutic agents.n increase of the alkyl chain length of the alcohols.
